Tissue having high improved cross-direction stretch
View Patent ↗The present invention provides tissue products having an MD/CD Tensile Ratio less than about 0.95, yet relatively high geometric tensile strength, such as geometric mean tensile strengths greater than about 1500 g/3″ and more preferably greater than about 2000 g/3″. The combination of a tough, yet relatively supple sheet is preferably achieved by subjecting the embryonic web to a speed differential as it is passed from one fabric in the papermaking process to another, commonly referred to as rush transfer.
1. A tissue product having an MD/CD Tensile Ratio less than 0.95, a basis weight from about 45 to about 80 grams per square meter (gsm) and a GMT from about 1500 to about 3500 g/3″.
2. The tissue product of claim 1 wherein the GMT is from about 2200 to about 3000 g/3″.
3. The tissue product of claim 1 having a GM Stretch greater than about 22 percent.
4. The tissue product of claim 1 having a percent CD Stretch greater than about 10 percent.
5. The tissue product of claim 4 wherein the single ply tissue web is an uncreped through-air dried web.
6. The tissue product of claim 1 wherein the product comprises a single ply tissue web having a weight from about 50 to about 80 gsm.
7. The tissue product of claim 1 wherein the MD/CD Tensile Ratio is from about 0.80 less than 0.95.
8. A tissue product having an MD/CD Tensile Ratio less than about 0.95, a GMT from about 2200 to about 3500 g/3″ and a GM Stretch greater than about 22 percent.
9. The tissue product of claim 8 having a percent CD Stretch greater than about 10 percent.
10. The tissue product of claim 8 having a GM Slope less than about 10 kg/3″.
11. The tissue product of claim 8 having a Stiffness Index less than about 5.0.
12. The tissue product of claim 8 having a basis weight greater than about 50 gsm.
13. The tissue product of claim 8 wherein the product comprises at least one through-air dried tissue ply.
14. The tissue product of claim 13 wherein the at least one through-air dried tissue ply is uncreped.
15. A tissue product comprising cellulosic fibers and a wet strength agent selected from the group consisting of polyamide epichlorohydrin resins and glyoxalated polyacrylamide resins, the tissue product having an MD/CD Tensile Ratio less than about 0.95, a basis weight from about 40 to about 80 gsm, a GMT from about 1500 to about 3500 g/3″ and a GM TEA greater than about 40.0 g-cm/cm 2 .
16. The rolled tissue product of claim 15 having a percent CD Stretch greater than about 10 percent.
17. The tissue product of claim 15 wherein the GMT is from about 2000 to about 3000 g/3″.
18. The tissue product of claim 15 wherein the GM Stretch is greater than about 22 percent.
